Description

Technical Field

[0001] The utility model relates to the technical field of sedimentation tanks, in particular to a sedimentation tank for fuel oil processing. Background Technique

[0002] The sedimentation tank for fuel oil processing refers to a device that places the processed fuel oil through the sedimentation tank during the production and processing of fuel oil, so as to precipitate the impurities inside the fuel oil, thereby ensuring the purity of the fuel oil. Publication No.: CN212818608U discloses a sedimentation and separation device for the production of thick camellia seed oil, including a sedimentation barrel, a filter screen, a detection tube, and an oil outlet pipe. Four groups of support legs are symmetrically welded and fixed at the bottom of the sedimentation barrel. The top of the sedimentation barrel is fixed with a top cover through bolts. A filter screen is slidably connected inside the sedimentation barrel, and the outer wall of the filter screen fits with the inner wall of the sedimentation barrel. A fixed plate is welded and fixed inside the sedimentation barrel below the filter screen. A detection tube is welded and fixed at the bottom of the fixed plate. Multiple through holes are opened on the detection tube. The detection tube extends outside the sedimentation barrel and is welded and fixed to the sedimentation barrel. An outlet is opened on the bottom plate of the sedimentation barrel, and an oil outlet pipe is welded and fixed inside the outlet of the bottom plate of the sedimentation barrel. This sedimentation and separation device for the production of thick camellia seed oil not only facilitates the effective cleaning of impurities in the camellia seed oil but also facilitates the spot inspection of the sedimented camellia seed oil. However, during the use of the above technology, the filter cover is fixed to the oil outlet pipe by screws, and the filter cover is located at the bottom of the sedimentation barrel, while the fixed plate is welded inside the sedimentation barrel. When the device is used for a long time, the sediment in the oil product will fall on the filter mesh of the filter cover. Over time, it may cause the pores of the filter mesh to be blocked by sediment or sludge, resulting in the inability of the sedimented oil product to be discharged from the sedimentation barrel through the oil outlet pipe in a timely manner, affecting the working efficiency of the discharge of the sedimented oil product, and it is impossible to effectively and quickly clean the filter cover. Therefore, improvement is needed. Summary of the Utility Model

A circular groove 21 is formed inside one end of the oil outlet pipe 6, and a sealing ring 22 is provided between the end of the filter pipe 7 inserted into the circular groove 21 and the bottom of the circular groove 21. This can improve the sealing performance at the connection between the oil outlet pipe 6 and the filter pipe 7 and avoid oil leakage. A clamping groove 14 is formed on the surface of the fixing seat 11, and the clamping groove 14 is aligned with the square groove 15 exactly. This is convenient for inserting the first insertion block 16 and the second insertion block 18 into the clamping groove 14. The number of the first insertion blocks 16 is two groups, and the two groups of first insertion blocks 16 are symmetrically distributed in the middle of the surface of the fixing block 12. The number of the second insertion blocks 18 is two groups, and the two groups of second insertion blocks 18 are symmetrically distributed on both sides of the middle of the surface of the fixing block 12.

[0025] Embodiment 2

[0026] Please refer to Figures 1-5, a square block 23 is fixedly connected to the surface of the precipitation tank 1. A threaded hole 24 is opened on the surface of the square block 23. A lead screw 25 is threadedly connected inside the threaded hole 24. One end of the lead screw 25 is fixedly connected to a clamping block 26. This facilitates the quick fixation of the lid 2 and also facilitates the disassembly and assembly of the lid 2. A limiting groove 27 is opened on the surface of the lid 2, and the clamping block 26 is slidably connected inside the limiting groove 27. This can limit the clamping block 26 stuck on the surface of the lid 2 to prevent it from rotating and affecting the fixation effect of the lid 2.

[0027] Working principle: During use, first add the oil product into the interior of the precipitation tank 1 through the funnel 5. When the oil product enters the interior of the precipitation tank 1, the filter screen 4 filters the impurities in the oil product. Subsequently, the filtered oil product falls to the bottom of the precipitation tank 1. After the oil product has precipitated in the precipitation tank 1 for a period of time, open the second valve 10, and the precipitated oil product enters the interior of the filter pipe 7 through the oil outlet pipe 6. The filter plate 13 inside the filter pipe 7 performs secondary filtration on the oil product. When the device has been used for a long time, sediment or sludge in the oil product may accumulate near the surface of the side of the filter plate 13 facing the interior of the precipitation tank 1, resulting in blockage of the pores of the filter plate 13. When this situation occurs, close the second valve 10, press the first push rod 19 and the second push rod 20. After being squeezed, the first insertion block 16 and the second insertion block 18 slide inside the square groove 15 and squeeze the spring 17. Subsequently, separate the filter pipe 7 from the oil outlet pipe 6. Then, clean the sediment and sludge accumulated in the filter pipe 7 and wash the filter plate 13 to keep the pores of the filter plate 13 unobstructed. Subsequently, install the filter pipe 7 and the oil outlet pipe 6 together again, achieving the quick disassembly and assembly of the oil outlet pipe 6 and the filter pipe 7, facilitating the cleaning of the filter plate 13 inside the filter pipe 7, keeping the air of the filter plate 13 unobstructed, and preventing sediment and sludge in the oil product from blocking the filter plate 13 and affecting the working efficiency of the precipitated oil product discharging from the precipitation tank 1. When it is necessary to clean the filter screen 4 inside the precipitation tank 1, rotate the lead screw 25. The lead screw 25 drives the clamping block 26 to move upward. Then, rotate the clamping block 26 to make the clamping block 26 away from the lid 2. Subsequently, remove the lid 2 and take out the filter screen 4 to clean the impurities inside the filter screen 4. This achieves the quick disassembly and assembly of the lid 2, improving the working efficiency of cleaning the impurities inside the filter screen 4 in the precipitation tank 1. By setting the limiting groove 27, the clamping block 26 stuck on the surface of the lid 2 can be limited to prevent it from rotating and affecting the fixation effect of the lid 2.

Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution content of the present utility model still fall within the protection scope of the technical solution of the present utility model.
